HAY -TEDDER.

SPECIFICATION forming part of Letters Patent No. 768,270, dated. August23, 1904. Application filed'June 8,1904. Serial No. 211,588. (No model.)

T0 00% whom, it may concern:

Be it known that I, HENRY M. CosEY, a citizen of the United States,residing at Sterling, in the county ofVVhiteside and State of Illinois,have invented certain new and useful Improvements in Hay-Tedders; and Ido declare the following to he a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference belnghad to theaccompanying drawings; and to the figures of reference marked thereon,,which form a part of this specification.

' My invention relates .to hay-tedders, and is specially designed foruse in that class of such machines wherein the hay is scattered by aseries of substantially vertical tedder-arms provided at their lowerends with spring teeth or forks and adapted to successively stir the haywith a kicking movement while the machine is in motion.

In practice in machines of this class ingoing in the same dirjectionwitha strong wind the hay is blown up into the tedder-arms, choking thecrank-shaft by which they are' operated until the driving-wheels slideupon side elevation, showing the movement of the slats 9. Fig. 4 is anupper end view of one of the slats 9 and support therefor. v

1 represents the frame of the machine supported on carrying-wheels 2,provided with in- It is quite common for the operator ternal gears 3 ontheir inner faces, 4 tare the usual fork-arms provided with springforks5. 4

Extending rearwardly from the frame 1 is -a pair of supports 6, unitedat their upper ends by a cross-piece 7, having on its rear face a seriesof loops 8. f Loosely held by the loops 8 is a series of slats 9,preferably constructed of wood, such slats being rigidly united by across-piece 10. A continuous crank-shaft 11 is journaled at each end inthe supports 6 and loosely attached to the cross-piece 10, so as tocause the slats 9 to simultaneously vibrate upon the rotation of suchshaft. On the frame 1 is supported a short post 12, in the upper "end ofwhich is journaled ashort shaft 13, havingcfixed on its outer end agear-pinion 14, meshing with and actuated by the gear 3 on'one of thewheels 2. Between the pinion 14: and post'12 is a sprocket-wheel 15,also fixed on the shaft 13 and connected by a sprocket-chain 16 with asprocket-wheel 17 on the end of the crank-shaft 11. By this meansrotation is imparted to the shaft 11 while the machine is in operation.This mechanism can be duplicated at the other side of the machine, ifdesired.

The slats 9 are so. disposed upon the crosspiece 7 as to alternate withthe fork-arms 1, and the forward'ends of the slats are tapered sothat-the forks will not come in contact therewith in their upwardmovement." By

the vibration of the slats 9 they are caused to move in a downward andslightly rearward direction so as to fan or beat the hay downwardly andprevent its being blown into the tedder mechanism. The operation of theslats is shown in Fig. 3, the upper ends of the slats projecting.sufliciently beyond the loops 8 to What Iclaim as my invention, anddesire in the supports 6, and loosely secured to the 10 to secure byLetters Patent of the United cross-piece 10; and means for rotating theStates, is* shaft 11; substantially as shown and set forth.
